Spelunking seems like an extremely dangerous hobby, and truly terrifying for people who have a problem with confined spaces, bats, and the dark.

Those who choose to take up spelunking spend a lot of time exploring underground to earn their stripes, and they learn to deal with unpredictable, and potentially life threatening, situations that often seem to pop up out of nowhere:

The fellow in this video has clearly earned his stripes, and yet nothing could prepare him for the time he got wedged in between the walls of a narrow rock "tube", as water started pouring in all around him.

Apparently it took him three hours of crawling to make his escape from Lost John's Cave on Leck Fell in Lancashire, England, but I imagine at that point he was just happy he didn't drown!
